Notification objects are not tightly related to the page that created them, and should be decoupled from the page.

- Create one NotificationPresenter that handles all notifications.
- Add ref/deref to the notification objects when they are added/removed from the queue of active notifications. The same technique is used for XMLHttpRequest.
- Instead of deleting all notifications associated with a page when the page is navigated, delete them on a timer, using the same timeout that QSystemTrayIcon is using.
- Break up the show() method into smaller methods.
- Use OwnPtr instead of raw pointer for QSystemTrayIcon.
- Move creating the QIcon to just before showing it in the QSyetemTrayIcon.
